What is it?An ultra-low noise microphone preamplifier. DetailsDesigned for use where long lines need to be driven or where conversion from mic level to line level is required, the Alice Mic-Amp-Pak is available in two versions: the single-channel Mic-Amp-Pak 1 and the dual-channel Mic-Amp-Pak 2. Both models feature switchable 48V phantom power and a switchable 80Hz high-pass filter plus front panel gain adjustment from 35dB to 75dB. Audio inputs and output are via Neutrik XLR connectors. Rack mountable (with the RPK-1 adaptor), the Mic-Amp-Pak offers a frequency response of 20Hz - 20kHz (+0dB/-0.5dB) and maximum THD of 0.009% (1kHz). Equivalent input noise is quoted at -131.3dB (150 ohm; 30Hz - 30kHz) and crosstalk is better than -90dB (at 1kHz). The balanced inputs are rated at 3k ohms impedance and maximum input level is -10dBu. The balanced and floating output provides an impedance of <1 ohm at a maximum output level of +26dBu.
